New description: [New technical field] • This creation is about a chamfer drill, especially a labor-saving chamfer drill that is easy to operate. [Prior Art] The existing chamfer drill is mainly provided with a drill portion at one end of a grip portion, so that when the user holds and rotates the chamfer drill, the drill portion can be positioned at a center position on a workpiece. Or forming a _ chamfered portion on the periphery of a hole opening. However, the drill bit of the chamfer drill is integrally connected to the grip portion. Therefore, when using the user, the user often needs to hold the grip portion with one hand, and then rotate the grip portion with another hand to smoothly rotate the handle. Angle drill, this will cause inconvenience and trouble in the operation of the existing chamfer drill. In addition, in the existing chamfering drilling operation, the user often needs to remove the hole in the working piece that needs to enter the (four) corner after turning the chamfering drill ring, and then turn the chamfering drill back, and then insert it back. In the hole, the chamfering operation is carried out again. If this operation mode is not only the whisker and the effort, it will be continuously removed and inserted into the chamfer drill, so that the chamfer drill easily deviates from the center point of the hole, resulting in the chamfer angle. Inaccurate skew, affecting the quality of the chamfering work. [New content] ' Therefore, the creator has a lack of structure and use of the existing chamfer drill. After continuous experimentation and research, the author finally developed a creation that can improve the existing defects. The main purpose of this creation is to provide a chamfer drill that can achieve 5 M333248 with one hand for ease of operation and effort. In order to achieve the above objectives, the present invention mainly includes: & for a chamfer drill, the main 'in the grip portion - the end recess is provided with a receiving hole. A sleeve, one end of the sleeve is inserted in the grip hole The tube is provided with a one-way bearing n* in the hole, a sleeve-inserted to the drill bit on the sleeve, the drill spoon, a one-way bearing in the tube, and one end of the rod is provided with two: one through sleeve > drill bit. By means of the above technical means, the creation can rotate the grip portion to complete the center point positioning or chamfering: the early drilling # is more convenient and labor-saving, to improve the practicability of the chamfering drill. By. = chamfering drill does not need to move the chamfer drill away from the hole of the person's corner in the chamfering operation to avoid the chamfer drill from deviating from the center of the hole, resulting in the skew of the chamfer angle, thereby increasing the chamfer The quality of the work [Implementation] 'This creation mainly provides a chamfer drill (1〇), please refer to the first to third figures, as can be seen from the figure, the main part of the chamfer drill (10) of this creation (1) a sleeve (10) and a drill portion (10), wherein the second end is provided with a receiving hole (122), and the sleeve (10) end is inserted into the receiving hole (122) in the sleeve (14) One end of the insertion receiving hole (122) is provided with a magnet (144), the other end of the sleeve (14) is provided with a one-way bearing (142), and the drill portion (16) is inserted into the sleeve (14). Wherein the drill portion (16) includes a plunger (162) extending through the one-way bearing (142) of the sleeve (14), and the end of the plunger 6 M333248 (162) is provided with a drill having at least one edge (164). When knowing, the eye is matched with the four drawings of the brother, because the one-way bearing (142) is arranged in the sleeve (14), and the plunger (162) of the drill portion (16) is inserted into the tooth. Bearing (142), so when the handle portion (12) is rotated in a specific direction, such as clockwise direction, the drill portion (16) will follow the sleeve (14) due to the one-way clamping of the one-way bearing (142) and The handle portion (12) rotates, and if the handle portion (12) rotates in the reverse direction, such as counterclockwise, the one-way bearing (142) can be idling relative to the insertion force (162), so that the drill portion (16) It does not rotate with the handle (12). Therefore, the user only needs to hold the handle portion (12) with one hand, and then repeatedly rotate the handle portion (12) back and forth to utilize the drill portion (16). The drill bit (164) completes the work of the middle to the point or the chamfering, so that the operation of the chamfer drill (j 〇) can be more convenient and labor-saving, so as to improve the practicality of the chamfer drill (1〇). The magnet (142) provided in the sleeve (14) can provide the plunger (162) of the drill portion (16) - the force of magnetic attraction, so that the drill portion (16) is not easily detached from the sleeve (I. In addition, The chamfer drill (1〇) of this creation can continuously insert the chamfer drill (1〇)_ into the hole to be chamfered during operation, and the chamfer drill (10) need not be moved in the chamfering operation. Leaving the hole, not only can the convenience of the operation of the chamfering drill (1〇) be improved, but also the chamfering drill (10) can be prevented from deviating from the center of the hole, thereby causing the skew of the chamfering angle, thereby improving the chamfering operation.
